Application filed December 27, 1920. Serial 1%. 433,195;

To all whom it may concern.

Be it known that I, WILLIAM A. MALONEY, a citizen of the United States,residing at Newton, in the county of Middlesex and State ofMassachusetts, have invented a new and useful Detachable Rubber Heel, ofwhich the following is a specification.

This invention relates to a rubber heel adapted to be detachably securedto a shoe. It is highly desirable that such a heel shall fit closelyagainst the shoe around the edges thereof and that the parts shallcontinuously maintain close contact.

It is an important object of my invention to provide means by whichclose and permanent contact may be maintained between the heel and theshoe so long as the heel remains in use.

With this general object in view my invention in its preferred formcontemplates the provision of a stiff wire or rod embedded in the heeland extending continuously adjlaceint the sides and curved rear wall ofthe I further provide an attaching device extending beneath the wire orrod at each side of the heel by which means a direct upward pull iscommunicated to the heel near the edge thereof, thus holding the partsfirmly in contact.

My invention further relates to arrangements and combinations of partswhich will be hereinafter described and more particularly pointed out inthe appended claim.

A preferred form of my invention is shown in the drawings in which- Fig.1 is a longitudinal sectional view of my improved heel attached to ashoe;

Fig. 2 is a bottom view of the heel lift which is permanently secured tothe shoe; h Fig. 3 is a plan view of the detachable eel;

Fig. 4 is a sectional view of the heel lift, on the line H in Fig. 2;

Fig. 5 is a sectional view of the detachable heel on the line 55 in Fig.3; and

Figs. 6, 7 and 8 are perspective views of detail parts to be described.

Referring to the drawings, my improved heel construction comprises aheel lift 10 permanently secured to the shoe 11 and a detachable heel 12commonly formed as a single block of molded rubber. Projections 13 onone of the parts fit closely in recesses 14 in the other part, thuspreventing relative angular movement of the parts;

In the manufacture of the detachable heel 1" 12 I place a wire or rod 15in the mold so that it is entirely embedded in the rubber and extendscontinuously along the sides and rear portion of the heel, adjacent theouter surface thereof but spaced slightly inwardly therefrom.

- I also provide a metal plate 16 extending transversely of the heel andhaving its outer ends disposed beneath the wire 15. The outer ends ofthe plate are preferably notched or shouldered as shown in Fig. 8 andthe shoulders engage the wire 15, thus preventing relative transversemovement between the plate and the heel. The plate 16 is provided nearits center with an upwardly enlarged projection 17 by which the heel issecured to the shoe.

Any suitable fastening or locking means may be provided for thussecuring the heel to the shoe, such, for instance, as are disclosed inmy pending application, Serial No. 383,668, filed May 24, 1920.

These fastening devices are shown in Figs. 2, 6 and 7, said devicescomprising a looking plate 18 mounted to slide lengthwise of the shoeand a holder 19 for said plate embedded in the heel lift 10. Ihe holder19 has a slot 20 and the locking plate 18 has a slot 21 enlarged at itsrear end.

In assembling the parts the projections 13 are inserted in the recesses14 and the projection 17 is inserted through the slots 20 and 21, thelocking plate being in its forward position as shown in dotted lines inFig. 1. The plate 18 is then pushed rearward, bringing the projection 17into the narrow portion of the slot 21 and holding 9 the parts firmly inposition.

As any tension on the projection 17 is transferred through the plate 16to the wire 15, it will be seen that the upward pull of the lockingplate is communicated to the outer edges of the heel, thus holding theouter portions of the heel in close contact with the heel lift attachedto the shoe.

Having thus described my invention. it will be evident that changes andmodifications can be made therein by those skilled in the art within thespirit and scope of my invention as set forth in the claim and I do notwish to be otherwise limited to the details herein disclosed but what Iclaim is 2- A rubber shoe-heel comprising a detachable rubber heel, acurved wire embedded in saidrubber heel and. extending continuouslyadjacent the sides and rear curved surface of said heel, and means tosecure said heel to the shoe, said means comprising a rigid metal plateextending transversely of said heel andembedded therein with its sidesperpendicular to the lower face of said heel and with its ends formedwith shoulders and reduced extensions both engaging said wire on thelower and inner 1 sides of said wire, said plate being also providedwith an upwardly enlarged integral projection at the middle portion ofits upper edge and said shoe having a co-operating locking devicefastened thereto whereby the edges of said rubber heel are positivelyforced into firm vengagement with the loottom of the shoe.

In testimony whereof I have hereunto affixed my signature.

WILLIAM A. MALONEY.
